Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584422, here are decompositions:

61 + 31584361 = 31584422
211 + 31584211 = 31584422
229 + 31584193 = 31584422
283 + 31584139 = 31584422
379 + 31584043 = 31584422
433 + 31583989 = 31584422
439 + 31583983 = 31584422
613 + 31583809 = 31584422

Showing the first eight; more decompositions exist.
